Mission
The Northwest Power Pool Corporate mission is to support electric reliability through cooperation
4
Vision
Helping the Northwest Power Pool members work together to maintain a reliable and secure interconnection – today and in the future
5
Values
• Member Driven• Relationship Based• Independent• Respect• Integrity• Trust• Competence
6
Work Environment• We support each other and create “safe” environment• Team concept• Merit-based compensation is satisfactory, i.e.,
comparable to industry• Openness• Trust• Respect • Integrity• Quality of work – pride in doing a good job• Job Security – to do the right thing at the right time
7
History
• First pooling of resources occurred in1917 in the Northwest
• NWPP formed in 1941 by 6 investor-owned utilities 3 staff engineers
• An impetus from the War Production Board in 1942 Ten major private utility systems and Bonneville Power
Administration Pooled resources to provide power to the war industries
• Maintained after WWII for reliability and coordination

Participant’s Vision
The Northwest Power Pool Membership Agreement serves as a forum for reliability and operational adequacy issues in the area for both transmission and generation.
17
Four Main Membership Committees
• Operating CommitteeOperating Committee Foster coordination and communication.
• Coordinating Group Coordinating Group Administer the Pacific Northwest Coordination Agreement,
optimizing Columbia Basin hydro generation.
• Transmission Planning CommitteeTransmission Planning Committee Provide a forum for reliable transmission planning.
• Reserve Sharing CommitteeReserve Sharing Committee Administer and address Contingency Reserve.
18
Operating Committee
• Adequacy Assessments - to assess the NWPP ability to meet and sustain load demands at all times including extreme load conditions as a result of weather or loss of generation
• Under-frequency Load Shedding - to arrest frequency decline in the event of a contingency such as severe generation/load imbalance.
19
• Outage Coordination - to coordinate the schedule of transmission outages enhancing system reliability and reducing the number of hours under constrained conditions
• Emergency Response Team - the ability to respond to current reliability issues such as extreme temperature conditions creating extreme load
Operating Committee
20
• Next Day Operating Studies Curtailment studies are performed by the individual path
operators based on the outage schedule developed through the COS process.
COS process – studies are performed at least 15 days prior to the outage
Includes all facilities 100 KV or greater Includes all generators 50 MVA or greater
Operating Committee
21
• NERC Active participation Coordinated information, discussions, interpretations and
responses
• WECC Coordinated discussions concerning new criterion,
interpretations and responses
Other OC Services
22
PNCA Coordination
• Critical Period Planning: That period in the historical water record that meets the least amount of firm load
• Previously the Critical Period was 4 years, but now 7 months
• Output of planning process are operating curves for reservoirs and FELCCs the systems
23
Coordinated Reservoir Operations
• Actual Energy Regulation FELCCs and curves from the planning process Actual and estimated streamflows
• Proportional draft• Energy in lieu of water• Provisional energy
24
Transmission Planning Committee
• Serve as a Forum for open discussion• Sub-Regional Studies to identify
Transmission options within a Sub-Region Multi Subregional Studies (requested by governmental agencies) Connections to Regional Transmission Parities with similar interests and goals – local stakeholder involvement Local costs and reliability benefits
• Assist in Regional Transmission Dispute Resolution Process• Collection and coordination of TPC members’ data including submittals
to WECC• Subregional collection and coordination for the NWPP area for WECC
submittals• Develop guidelines for assessing the reliability and efficient
development of the transmission system in the NWPP area
25
Reserve Sharing Committee
• Contingency Reserve Sharing to provide 60-minute recovery assistance on a “flow base” Concept – one very large area operating as a single BA
for contingency reserve
26
• Northwest Operational Planning Study Group (NOPSG) Closed process (OC and TPC members) Seasonal path operating studies
• UFLS studies • Seasonal Assessments
Summer and Winter Long-Term Resource Assessments
Transmission Planning Committee and Operating Committee
27
• Long-term Significant Outage Planning (LTSOP) Share outage information with all parties affected by outages
of significant equipment (i.e., equipment that affects the transfer capability of rated paths). Information is shared two times each year for a minimum of a six-month period. The first meeting each year coordinates outages for July through December. The second meeting coordinates outages for January through June.
Review the outage schedules to insure that needed outages can be reliably accomplished with minimal impact on critical transmission use.
Outage coordinators are to post the outages on the Coordinated Outages System within the applicable timeframes.
Transmission Planning Committee and Operating Committee
28
• Local Load Voltage Protection Facilitate the process to comply with the WECC criteria
and guidelines as applicable.
Participate in studies determining minimum requirements for compliance with the criteria and guidelines when more than one Transmission Operator is involved.
Develop and publish final reports
Complete the necessary documentation and provide copies all involved entities.

• Under Frequency Load Shedding Process Facilitate the process to comply with the NERC
Reliability Standard and WECC criteria and guidelines as applicable.
Participate in studies determining minimum requirements for compliance with the criteria and guidelines for the NWPP Area
Develop and publish final reports
Complete the necessary documentation and provide copies all involved entities.
